DRAWER-OPERATING MECHANISH.

Application filed December 1, 1919. Serial Ro. 841,000.

To all whom it may concern.

Be it known that I, CLIFFORD NADEN, a citizen of the United States, residing at Boise, in the county of Ada and State of 6 Idaho, have invented certain new and useful Improvements in Drawer-Operating Mechanism, of which the following is a specification, reference being had to the accompanying drawings.

10 This invention relates to certain improvements in drawer operating mechanism, and has relation more particularly to a mechanism desi ned and adapted for use in connection with a cash drawer or the like, and

it is an object of the invention to provide novel and improved means wherein the mechanism is adapted for use in connection with the 0 rating lever of an adding machine, so thzt an adding machine may be employed to keep record of the amounts inserted within or withdrawn from the drawer, and the total therein.

Another object of the invention is to provide a drawer operating mechanism which coacts with the drawer in a manner to lock the same in a closed position, together with means for automaticall movmg the drawer in an open or exten ed positlon upon movement in one direction of the operating lever for an adding machine arranged in juxtaposition with respect to the drawer.

An additional object of the invention is.

wherein novel and improved means is arranged within the structure for holding the drawer in a closed or restricted position, together with means for automaticall o ning or extending the drawer when t e rstmentioned means is rendered inoperative throu h the instrumentality of the pull lever of the adding machine when moved in one direction.

A particular object of the invention is to or provide a novel and improved drawer operating mechanism under control of the pull lever of an adding machine, whereby a conventional style of adding machine may be employed in connection with a cash drawer or the like and the mechanism therefor in a manner to produce a combination of parts which may be employed with substantially the same facility and convenience as the cash register now in use, and wherein the further advantage is provided in permitting the adding machine to be displaced or removed to permit its use independently of the drawer operating mechanlsm.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved drawer operating mechanism whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advanta eous for use, as will be hereinafter more ully set forth.

The novel features of my invention will 30 hereinafter be definitely claimed.

In order that m invention may be the better understood, li will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in perspective illustratin a drawer operating mechanism arrange in accordance with an embodiment of my invention;

Figure 2 is an enlar ed fragmentary view partlyin section an partly in elevation illustrating a mechanism arranged in accordance with an embodiment of my invention;

Figure 3 is a fra entary view partly in section and partly in elevation illustrating the mountin of the late as herein employed and t e expansi le member coacting therewith, and,

. Figure 4 is a fra entary view partly in section and partly in elevation illustrating an operating mechanism constructed in accordance with a further embodiment of my invention. 7

As disclosed in the accompan drawings, C denotes a cabinet of desir confi tion and dimensions, and which has sli ably entering therein through its forward face 1 a drawer D, of a type generallmmplo ed in stores for cash receipts. The tom g of the cabinet is provided with the anti-friction members 3 with which the drawer D engages, so that said drawer may be extended or retracted with respectto the cabinet C the hook member 6. The latch L comprises an elongated member having its end portion remote from the drawer D, pivotally engaged, as at 8, with the upstanding plate 9, said latch having swinging movement in a vertical direction. The working end portion of the latch L is provided in the upwardly facing lock 11, which coacts with the hook member 6 in a conventional manner. The plate 9 is positioned within the space between the rear wall 5 of the drawer, and the rear wall 4 of the cabinet when the drawer is in its closed or retracted position. The plate 9 is preferably oblong, with its flat faces vertically disposed, and the lower longitudinal margin of said plate is defined by the outstanding flange 12, substantially at right angles to the plate 9. The flange 12 is secured to the bottom 2 of the cabinet I? by the screws 14 or other anchoring memers.

The latch L is constantly urged upwardly through the instrumentality of a spring leaf 15, having one end portion "anchored as at 16, to the plate 9 at a point below the latch B and preferably in close proximity to its pivotal, mounting 8. The spring leaf 15 has its opposite end portion bearing against the lower ed e of the latch L. The latch L is prevente against upward swinging movement beyond substantially the horizontal, by an outstanding stop 'lug 17 carried by the plate 9, and with which the upper edge of the latch L engages when the latch L is free of the hook member 6. In other words, the lug 17 operates to maintain the working end of the latch L in a position to properly engage the hook member 6 when the drawer is retracted or moved inwardly to closed position. I

When the drawer is retracted or moved inwardly to closed position it compresses an expansible member 18, herein disclosed as a coil spring. One end portion of the member or spring 18 is engaged with an outstanding bracket 19 carried by the late 9 at a point below the latch L, and pre erably below the spring 15.

The opposite end portion of the member or spring 18 contacts with the rear wall 5, so that when the latch L is disengaged from the hook member 6, said member or spring 18 operates to automatically throw the drawer D into an extended or open position.

The top wall 20 of the cabinet C,-at a point above the latch L is provided with an opening 21, in which seats a flanged bushlng 22. Secured to the upper surface of the top wall 20, and overlying the outer face of the bushing 22 is a second upstanding bushing 23, which serves to maintain the bushing 22 in applied position, and the bores of the bushings 22 and 23 are in register.

Slidably disposed through the bushings 22 and 23 is a push trip P. The push tri P comprises two sections, 24 and 25. The upper section 24 is provided in its inner-or lower end with a socket 26, in, which is threaded the upper end portion of the lower section 25, and which section is provided with the peripheral threads 27, extending the entire length thereof. By this coaction between the sections 24 and 25 a push trip P may be extended or shortened, as the requirements of practice may necessitate, and said sections are maintained in their relative adjustment through the medium of a lock nut 28, which engagesthe inner or lower end of the section 24. The nut 28 also serves as a stop for contacting with the inner or lower end of the bushing 22 or the inner face of the top wall 20, to limit the upward-or outward movement of the push trip P.

The push trip P is constantly urged upwardly through the medium of a leaf spring 29 having one end portion anchored, as at 30, to the upper portion of the plate 9. The opposite end portion of the spring 29 contacts with and bears against the inner surface of the. nut 28.

In practice the sections 24 and 25 of the push trip P are relatively adjusted, so that when the push trip P is at the limit of its upward or outward movement, the lower or. inner end of the section 25 will be substantially in contact with the upper or adj acent edge of the latch L, so that upon depression of the push tri P to the requisite extent, the latch L will e disengaged from the hook member 6. so that the drawer D may be automatically extended or opened through the instrumentality of the expansible member or spring 18.

The upper or outer end of the section 24 of the push trip P is provided with a recess or pocket 31, in which is rotatably mounted a roller 32, a portion of said roller extending beyond the adjacent end of the section 24. The roller 32 affords an anti-friction means for coaction with the hub portion of the pull lever B of an adding machine to be hereinafter more particularly referred to.

The adding machine A may be of any type, but preferably of a style embodying a pull lever B at a side thereof. The machine A, as disclosed in the accompanying drawings, is of the Dalton type, but I do not wish to be understood as limiting myself in this respect. The machine A is adapted to be set upon the cabinet C with the pull lever B thereof, or more particularly the hub 33, directly above the push trip P, and with which hub the roller or anti-friction member 32 normally substantially contacts. An adjustment of the sections 24 and 25 of the push trip P assures a proper setting of the push trip P to assure this contact or engagement.

The hub 33 is provided with a cam 34, and when the lever B is pulleddownwardly to efiect the requisite operation of the mechanism of the machine A, the cam 34 operates to furnish the push trip P downwardly to release the drawer D, and resulting in an automatic opening or moving of the drawer into open position.

This particular combination with an adding machine A permits a merchant to have a fixture operating with substantially the same advantage as a cash register of any of the types now/generally employed, with the further advantage that the machine A may be readily removed from the cabinet C or displaced with respect to the push trip P to permit an independent use of the machine A when the occasions of practice may require. By this means a merchant or the like, with a small outlay of money is possessed of the advantages of botlf a cash register and an adding machine.

Although forming no particular part of my invention, it is to be understood that the adding machine A may be provided with ex- I tra keys, such as Pd. out, Reed. acct.

For clerk letters, etc.

In Figure 4 I disclose a modified structure for effecting a release for the cash drawer when the ull lever of the adding machine is operated The latch L is supported in substantially the same manner as the latch L hereinbefore referred to but the working end of said latch L is provided with a downwardly facing hook member 36 which engages an upwardly facing hook member 37, carried by the drawer. 38 denotes an upwardly extending member having one end portion provided with a longitudinally directed slot 39, through which is directed a member 40 carried by the latch L, whereby the latch L swings upwardly upon raising of the member 40. The opposite end portion of the member 38 is provided with an elongated socket 41, in which is threaded an end portion of an elongated member 42, whereby said members 38 and 42 may be adjusted longitudinally one with respect to the other in accordance with the requirements of practice. 43 denotes a lock nut engaged with the member 42, and coacting with the adjacent end of the member 38, whereby said members 38 and 42 are held in their desired adjustment. The member 42 extends exteriorly of the cabinet C through the top wall thereof, and to said outer or upper end portion of the rod 42 is pivotally engaged an end portion of a rod 44. The opposite end portion of the rod 44 is engaged with a crank 45, carried by the outer end of the operating shaft 0 with which the pull lever B coacts.

From the foregoing description it is thought to be obvious that a drawer operating mechanism constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention'is susceptible of some change and modification without departing from the principles and spirit thereof. and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
